Partition Logic

  • More than one person uses the computer and you want to keep separate files—and access rights—for security reasons. Partitioning can be particularly helpful when you share a PC with a child.

  • You want to squeeze more performance out of your PC. Partitioning a large drive into smaller units improves performance by decreasing the amount of travelling the drive’s read/write head has to do when it searches for data. A partition also shrinks the size of the tables the computer uses to keep track of where data is stored, further improving performance.

  • You want to make your system more manageable. If you keep your operating system and applications on a partition separate from your data, the data will be easier to back up and easier to restore. What’s more, if you need to reinstall the operating system, you can do it without worrying about the data on the other partition.
